I 5 Claims.

This invention relates to 'a container orieceptacle made ofcardboard;paperboard orally other material having similar pllability, stiffnessand elasticity. Such receptacles-are useful, for example, as portablesputum boxes.

An object ofth'e invention is to providea container-or said type whichhas -a cover or-"lid hinged to the up er edge of oneof the side walls ofthe container.

-Otlier objects are to make said cover selfclosing, easily to be liftedand to provide selfclosing means of proper resiliency and which donotrequire additional material, andpan'beeasily assembled.

Further objects are' to provide a hinge connecting thecover with-a sidewallofit-he box andactingas a s ring exerting-a sllg ht'pressiire whichtends to close the coven'to form said hinge from an integral part of'the sheet material form ing as cover. to avoid the" need ror at-width ofthe material forsaid-hing exceeding the width of thecover-or of the'side wall, to provide spring action by parts out from-the inner portionof the hinge material, and to make the resilient hinge so that it can bequickly and easily assembled.

Still further objects are to make the box and the cover so that they canbe made from a single integral sheet of flat material, to avoid waste ofmaterial, and to make the box and the cover inexpensive, reliablyoperating and light of weight.

These and other objects are achieved as will be apparent from theillustrative embodiment described in the following description andillustrated in the accompanying drawing in which:

Fig. 1 shows a plan view on a reduced scale of a flat sheet from whichthe embodiment is assembled.

Fig. 2 shows a perspective view of the assembled embodiment.

Fig. 3 shows a view of the hinge and the adjacent part of the cover,seen from above, the

remaining part of the cover being shown broken off.

Referring to the drawing, numeral l indicates the bottom of the box 2and 3 are two opposite side walls (left and right side in Fig. 2). Theremaining side walls are assembled from several folded portions of theoriginal sheet, one set of portions 4, 5, B, 8, 9 and I being used toform each of said latter walls in the following manner: The portions 6and I are folded together at their separating line, this line going tothe outer side. Then and '1 together are folded until 1 tou'chesthe'outer --side ohm-whereb the left edge of 4 comes into contact withthe corresponding edge of 2, The portions Wand tare toldedin the sa'meway-whereby the right edge of 4- comes-into contact *with thecorresponding edge oft. 'Then-the portion i lsbent down to the outer-side, -arid the extenslons 40 or '5 are slip under the folded portions651mm 8,*'9; respectively, whereby the wall is assembled. Said rom wamtogether'wltnsaid bottom rorm a cup like receptacle.

The hinge 'lsrormedh'oirr the portions 'l l and l2-as will be desc'rlbedlater. -Thenbter l3'i's slightly larger than the opening formed by "theu eredges of the assembled wall wher'eb the cover-whenclosed='-r-estsupon-said edges and covers reliably the content-cr meboxfThe'ilinge and the cover 1 8 formone extension or the side wall 3.rrferslbiy me-eiitireboxismade from one undivided-sheetand assembled bymere-folding atthe lines shown inFig." -1.

A number or narrow ribs 14, roiexample two,

formed by impressions preferably made from the lower side are running instraight lines across the cover 13 and serve to stiffen the cover and toincrease the spring action of the hinge. In the shown embodiment, theseribs extend as far as the line separating the two portions l I and I2 ofthe hinge.

Means to effect a spring-like pressure are provided within the hinge inthe following manner: Two symmetrical lines or thin slots l5 are outthrough the portions H and I2. These lines are straight, except at themiddle of H where each line forms a projection l6 toward the centralpart of II, The projections I6 form small tongues of about semi-circularshape. The cut lines 15 divid the hinge into a central part and twosymmetrical outer parts.

The hinge is assembled in the following way: The sheet is bent aroundthe line separating the portions 3 and II whereby the portions H, l2 and13 are brought into an about horizontal position. Then the sheet is bentaround the line separating H and [2 whereby H and I2 are I ioldedtogether and the cover I3 is brought into position, the tongues 5 pressthe central part of the hinge down and the reaction presses the tonguesand the lateral parts of the hinge up whereby the cover is resilientlypressed against the cup.

It will be noted that the means to efiect a spring-like pressure areformed exclusively from the inner material of the hinge. This factavoids any Waste of material while such waste would be unavoidable ifother pressing means would be used which project over the side edges ofthe hinge. The described arrangement further results in a relativelystrong and lasting spring action and makes possible an easy, quick andproper assemblage.

We desire it understood that our invention is not confined to theparticular forms and uses shown and described and that the invention maybe carried out in other ways without parting from the spirit of theinvention, as it is obvious that the embodiment described is merelyillustrative and represents only one of the many Ways in which anyoneskilled in the art may attain the objects and achieve the results of theinvention.

We claim:

1. A container comprising a cup-like part; a cover; and a hingeconnecting said cup-like part and said cover, said hinge comprising alongitudinally folded strip of pliable and elastic material divided intosections and pressing means formed by integral parts of said hinge,confined within the length of said hinge not longer than the width ofsaid cover and pressing said sections resiliently against each otherwhereby said cover is resiliently pressed, toward said cup-like part.

2. A container comprising a cup-like part; a

cover; and a hinge connecting said cup-like part and said cover, saidhinge comprising a longitudinally folded strip of pliable and elasticmaterial and divided by at least one cross-cut into several sections, atleast one section having a projection extending over the adjacent edgeof another section and adapted to he slipped beyond said edge wherebysaid two sections press resiliently against each other and said covertoward said cup-like part.

'3. A container comprising a cup-like part; a cover made of flat,pliable and elastic material and having at least one rib crossing thesurface of said cover; and a hinge connecting said cuplike part and saidcover, said hinge comprising a longitudinally folded strip of the samematerial as said cover is made of, divided into sections and pressingmeans formed by integral parts of said hinge, confined within the lengthof said hinge not longer than the width of said cover and pressing saidsections resiliently against each other whereby said cover isresiliently pressed, toward said cup-like part.

4. A container comprising a cup-like part; a cover; and a hingeconnecting said cup-like part and said cover, said hinge comprising alongitudinally folded strip of pliable and elastic ma terial dividedinto sections and pressing means formed by integral parts of said hinge,confined within the length of said hinge not larger than the width ofsaid cover, and pressing said sections resiliently against each otherwhereby said cover is resiliently pressed, toward said cup-like part,said cover and said hinge being made of one sheet having at least onerib crossing the line separating said cover and said hinge.

5. A container folded from a single sheet of pliable and elasticmaterial and comprising a cup-like part; a cover; and a hinge connectingsaid cup-like part and said cover, said hinge comprising alongitudinally folded strip divided into sections and pressing meansformed by integral parts of said hinge, confined within the length ofsaid hinge not longer than the Width of said cover and pressing saidsections resiliently against each other-whereby said cover isresiliently pressed, toward said cup-like part.
